Sonas has begun a demonstration experiment as the first applicant company in Tokyo Metro Co., Ltd.'s "Tokyo Metro ACCELERATOR (Railway Business Challenge Solution Program)." "Tokyo Metro is developing technology for the introduction of condition-based maintenance (CBM) using sensing technologies; however, traditional wired data communication has posed challenges such as construction costs for wiring and securing wiring space. This demonstration experiment will utilize Sonas Corporation's IoT wireless technology 'UNISONet,' which allows for the omission of wiring for data communication, to collect data such as temperature and humidity. This will verify the reduction of construction costs for wiring in subway station premises and the safety and effectiveness of wireless data communication." Quoted from: Tokyo Metro's official website.

An interview with our representative, Ohara, was published in the September 18 issue of Weekly BCN+. You can also view it on the website. (Free membership registration is required.)

In the March 2024 issue of "Railways and Electrical Technology," our company's "Pole Inclination Monitoring System" has been featured. The article highlights the case where a compact, lightweight, and simple Sonas system was adopted for the "Pole Inclination Monitoring System" to ensure the reliability of construction during railway overhead wire replacement work.

On April 10th, the Nikkei Shimbun morning edition featured Sonas's remote inspection service for analog meters. By automating the routine inspections of analog meters with this service, we can reduce inspection costs, prevent errors in recording, and enable more frequent monitoring. This service can be easily and cost-effectively installed without the need for power or network construction, and it is capable of accommodating a large number of units and wide installation areas. We encourage you to consider the introduction of this service.

The tilt monitoring system and wireless vibration measurement system have been re-certified as part of the seven IoT tools by Japan Management Association Consulting (JMAC). For more details on the seven IoT tools, visit: https://go.jmac.co.jp/article/category/kaizen-iot/
